    　View Summary

    Microbial electrochemical systems (MESs) rely on the microbes' ability to transfer charges from their anaerobic respiratory processes to electrodes through extracellular electron transfer (EET). To increase the generally low output signal in devices, advanced bioelectrical interfaces tend to augment this problem by attaching conducting nanoparticles, such as positively charged multiwalled carbon nanotubes (CNTs), to the base carbon electrode to electrostatically attract the negatively charged bacterial cell membrane. On the other hand, some reports point to the importance of the magnitude of the surface charge of functionalized single-walled CNTs (SWCNTs) as well as the size of functional groups for interaction with the cell membrane, rather than their polarity. To shed light on these phenomena, in this study, we prepared and characterized well-solubilized aqueous dispersions of SWCNTs functionalized by either positively or negatively charged cellulose-derivative polymers, as well as with positively charged or neutral small molecular surfactants, and tested the electrochemical performance of Shewanella oneidensis MR-1 in MESs in the presence of these functionalized SWCNTs. By simple injection into the MESs, the positively charged polymeric SWCNTs attached to the base carbon felt (CF) electrode, and as fluorescence microscopy revealed, allowed bacteria to attach to these structures. As a result, EET currents continuously increased over several days of monitoring, without bacterial growth in the electrolyte. Negatively charged polymeric SWCNTs also resulted in continuously increasing EET currents and a large number of bacteria on CF, although SWCNTs did not attach to CF. In contrast, SWCNTs functionalized by small-sized surfactants led to a decrease in both currents and the amount of bacteria in the solution, presumably due to the detachment of surfactants from SWCNTs and their detrimental interaction with cells. We expect our results will help researchers in designing materials for smart bioelectrical interfaces for low-scale microbial energy harvesting, sensing, and energy conversion applications.

    　View Summary

    Abstract

    Biosensors based on organic electrochemical transistors (OECT) are attractive devices for real‐time monitoring of biological processes. The direct coupling between the channel of the OECT and the electrolyte enables intimate interfacing with biological environments at the same time bringing signal amplification and fast sensor response times. So far, these devices are mainly applied to mammalian systems; cells or body fluids for the development of diagnostics and various health status monitoring technology. Yet, no direct detection of biomolecules from cells or organelles is reported. Here, an OECT glucose sensor applied to chloroplasts, which are the plant organelles responsible for the light‐to‐chemical energy conversion of the photosynthesis, is reported. Real‐time monitoring of glucose export from chloroplasts in two distinct metabolic phases is demonstrated and the transfer dynamics with a time resolution of 1 min is quantified, thus reaching monitoring dynamics being an order of magnitude better than conventional methods.

    　View Summary

    We report on the realization of polymer light-emitting diodes (PLEDs) based on fluorescent polythiophene (PT)-based insulated molecular wires (IMWs). PLEDs using PT emitting layers traditionally have low external quantum efficiencies (eta(eqe)) below 0.1%. Moreover, IMWs lack a thorough exploitation for electroluminescent applications due to concerns about reduced charge transport between their chains. We constructed multilayer PLEDs containing PT IMW emitting layers that show the maximum eta(eqe) close to 1.4%, luminance at 3700 cd/m(2), and low turn on voltage at 2.5 V. We also show a strong influence of the thickness of electron transport layer on eta(eqe) through device optimization and optical simulations.

Internal Special Research Projects

  • Towards Ultrasensitive Detection of Bacterial Extracellular Electron Transfer in Human Gut by Novel n-type Conducting Polymer Electrode Interfaces and Organic Microbial Electrochemical Transistor

    2023   Takahashi Tatsuhiro, Nagamine Kuniaki

    　View Summary

    In this phase, the goal of this research was to make electrodes that can sensitively measure the electrical signal of electroactive bacteria by maximizing the number of bacteria on the electrode surface. For this aim we used conducting nanomaterials that act as an interface between the base carbon felt electrode and bacteria. We utilized two different types of conducting nanomaterials, carbon nanotubes (CNTs) and conducting redox polymers through collaborations with two professors of Yamagata University.Specifically, me and my student at Waseda University have evaluated the electrical signal in electrochemical cells arising from the bacteria Shewanella oneidensis MR-1 metabolizing lactate, and transferring the released electrons from the metabolism to the carbon felt electrode with nanomaterial interfaces. For this aim we used potentiostats and the techniques of chronoamperometry, cyclic voltammetry and electrochemical impedance spectroscopy.In both types of materials, we observed a 3–4-fold increase in the measured current signal compared to not using the nanomaterials interfaces. Moreover, by scanning electron microscopy, we observed an increased number of bacteria on the electrode surfaces. A special point of the subproject containing CNTs was that twice we hosted a student from Yamagata University who prepared CNT-functionalized electrodes and measured the bacterial electrochemical performance with us, also teaching us a new way of chemical attachment of CNTs to our electrodes. As for the conducting polymer subproject, we not only tested electroactive bacteria, but also non-electroactive bacteria in electrochemical cells with promising results.Currently, we are preparing three manuscripts, and performing some missing experiments to complete the scientific papers, where we will explain our new results. In addition, our student will present the relevant results at the Spring meeting of Japan Society of Applied Physics. Finally, this grant (Tokutei Kadai), allowed us to buy a temperature-controlled incubator where we can stably evaluate the electrochemical performance of bacterial devices, as well as to purchase small-sized electrochemical cells to be used with flat-type substrates.

  • Towards Ultrasensitive Detection of Bacterial Extracellular Electron Transfer in Human Gut by Novel Functionalized Carbon Nanotube Electrode Interfaces and Organic Microbial Electrochemical Transistor

    2022   Okamoto Akihiro

    　View Summary

    Because a unique chance for collaboration between the National Institute of Materials Science (NIMS) and Waseda University (WU), we have modified this project to: “Monitoring pathogenic oral bacteria by electronic device and wireless signal transfer”. The project is divided into three parts: 1) detection of changes in the impedance of an electronic conductor upon the deposition of bacteria; 2) wireless sensing of such impedance changes; 3) development of an in-vivo device that can allow the wireless detection of oral bacteria. In this project, NIMS provides oral pathogenic bacteria and expertise of handling them, while WU realizes the electrical sensing, as well as the design and fabrication of a device for wireless detection. In FY2022 the applicant has visited NIMS to learn the immobilization and handling technique of the targeted bacteria. Measurements of the impedance changes of electrodes were performed upon the deposition of bacteria. This project continues in FY2023.
